Yep, true duals with SEPro's I got from 103Thunder here. Really seems to work. The neighbor just told me how nice they sound. 
Yep, I know I'm loving mine. I saw your reply on my "Pinging" thread, and like you said, I'm good to go for the summer. I'm beginning to get big eyes for some engine mods this winter..................and if my bonus check does me justice, then we'll go through with it. Need to get the pressed flywheel fixed, which means split cases, so may as well go up to 110" or 113", which also calls for gear drive cams, Feuling oil pump, lifters and support plate..............oh, and gotta have a Baker...................DAMN I have an appetite!
Mine do work well. I'm lovin' my exhaust. I did notice that Rod (tuner) had to drill through the small flat plate on one side of the inside of the muffler to get the A/F sniffer all the way up the header. I think they are MUCH louder now because of that......or it may just be that I'm hearing in stereo after the true dual install.
